Although having several 1 ton vans, I'm new to trucks - please tell me what differences to you find in running 19.5" tires vs. 18" tires.
The 19.5 tires are a medium truck tire and in the case of the Michelins that are on my truck have an "H" load factor and a 16 ply rating and a maximum load at 120 psi of just under 5000lbs which gives you a considerable safety factor when driving over rough or bad roads when carrying the type of heavy TC,s that are on the market being hauled by today's HD, SWD trucks.
You can expect more mileage from these tires but it comes at a price such as new wheels(Vision, Rickson, Alcoa), more $$$ for the rubber, cannot be aired down as low as a light truck tire( min. 85psi), wheel and tire heavier.
I am sure more folks will add to their experiences with 19.5's tires on their TC,s.
